The valve that lets the burnt gases out of the engine to the exhaust.
PROX offers this exhaust valve for HONDA CRF 70, XR 70 1997-2012. A four-stroke engine breathes through its valves. The exhaust valves open to let the burnt gases out to the pipe, then close again.
Titanium or steel valve?
The material is shown in the product name.
- Titanium: about 40% lighter than steel, it allows high revs without valve float; it costs more and its coating wears faster if the seats and guides are tired.
- Steel or stainless: heavier, but very wear-resistant and cheaper; as a replacement for titanium it lasts longer, with springs suited to its weight.
- Tip: replace valves as a set, have the seats checked and fit new valve stem seals.
Why choose PROX?
ProX valves come from Japanese OEM factories; the titanium versions are forged in one piece and chromium-nitride (CrN) coated against wear.
When should you replace the valves on your HONDA CRF 70?
Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.
